SYMPTOMS
========
Setting the Alignment property of a column in a DBGrid control at design- time,
before selecting Retrieve Fields, results in the grid not showing any data when
the application is run.
RESOLUTION
==========
At design time, select Retrieve Fields from the custom control property dialog
box. Any changes made to the Alignment properties of columns in the grid will no
longer cause this problem. If the DatabaseName and RecordSource properties of
the data control are not known until the program is run, using Retrieve Fields
won't be an option. In this case, just set the Alignment property of the
column(s) in question at run time, like this:
DBGrid1.Columns(0).Alignment = 2 'select center alignment
STATUS
======
Microsoft has confirmed this to be a issue in the Microsoft products listed at
the beginning of the article. We are researching the problem and will post new
information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Problem
--------------------------
1. Start Visual Basic.
2. From the File menu, choose New Project.
3. Click the DBGrid button in the Toolbox and drag a new DBGrid control onto the
form.
4. Double click the data control button in the Toolbox to add a data control to
the project.
5. Set the following properties of the data control:
DatabaseName: path to your vb directory\biblio.mdb
RecordSource: Authors
6. Set the DataSource property of the DBGrid control to Data1.
7. Right-click the DBGrid control and select 'Properties...' to display the
DBGrid's property dialog box.
8. Click the Columns tab, and change the Alignment property of the first column
to '2 - Center'. Press OK to keep changes.
9. From the Run menu, choose Start (ALT, R, S) or press the F5 key. The
application will start and the DBGrid will be displayed with the text
insertion icon in the center of the first cell. However, no data will be
visible. Printing out the contents of a cell's Text property gives an empty
string. Stopping the program, selecting 'Retrieve Fields', and starting again
fixes the problem.
